Hi Emily, Why 2 cell phones? I can barely remember to take the one I have with me? 
I think technology can help a lot… I confess I am in love… and so grateful for my husband’s Dexcom… since we have that thing, I feel I can sleep better and that I have a partner on taking care of Manuel, while we sleep, I know it sounds crazy, but I feel supported and not as helpless.
Still, I guess everything is relative, for some people technology its easier to manage and accessible… we were brainstorming the order day, what will happen to us if we were lost in an island… apart for insulin… without the blood glucose monitor, how will we know, even if Manuel only ate protein all day… and we had some fruit handy to treat lows… control will be out of hands… I guess we could have some ants on a jar (if we have a jar, lol) and feed them a drop of blood to analyze reactions… It is scary, I know… but yes, I think there is definitely some technology that PWD really needs, other is of course is optional or nice to have.
The sad part is that as we write this there are diabetic household with 3 or more blood glucose monitors (like ours) ans still many PWD does not have the means to test.
